Best teacher ever

Mannnn! A gem a I have found. How deeply he felt the topics and explained is such a joy learn !

my teacher gave notes that complicated this simple stuff into such complex equations with no explanation. with just an analogy you brought this into limelight. much thanks to you sir!

Thank you! My professor went on and on about how these were derived, but never really explained what the adjustments were for or why they were important. This is great, I really appreciate your videos!

Sir thank you for the videos i am an indian student aiming for higher studies and physical chemistry is where i would love to continue my journey .....you have provided us a very intuitive and logical course in short and concise videos...how i wish more people knew the beauty of this course🤝

Hi! Thanks for the videos, they're a great resource! I will be teaching PChem soon. Question: The work formula was derived using the definition of internal energy and microscopic pressure, both describing the system. So why is the macroscopic pressure in the general formula all of a sudden the external pressure? I am struggeling to understand where in the derivation the reversibility was assumed.

Thank you for this great video it explains very clearly the concept

Their is difference between gas and vapour but you use them alternatively 😢

🎉any jee aspirants any jee aspirants

Helped me a lot, congrats for the job

Good for jee advanced

But molar mass of benezne is 78??

Thank you so much for this video! My prof essentially hand-waved this topic and left us to study it on our own, so this was such a big help.

wow, are you writing backwards on the "blackboard glass"?

Thankyou so much.

this is a perfect video that helped me twice understanding the joule-thomson effect! thank you very muchh

Is he writing backwards or was the video flipped?

4:45 i found an error with the labeling of the states, the ground state is n=0 so the 5th is actually the fourth and the sixth the 5th that way the number of nodes are equal to n

Why is the external and internal pressure equal whenever you do it slowly? Wouldn't the internal pressure be greater than 1 all the way till the end?

thank you

Thank you so much sir !

Dr Stuart is excellent instructor.

Thank you very much! I can now understand how that actually works! You actually deserve much more subs and views than mere thousands! Btw a little fun fact: you didn't say "Joule Thomson Effect" in the whole video; anyways, it was interesting! Thanks again!

7:12 If the boundary condition is that our wavefunction psi(x,y,z) = X(x)Y(y)Z(z) = 0 when x = 0 or a, y = 0 or a, z = 0 or a, why do we choose to take X(x) = 0 when x = 0 or a, Y(y) = 0 when y = 0 or a and Z(z) = 0 when z = 0 ot a as our boundary conditions for the three Ordinary differential equations? We don't have to take these to satisfy the above boundary condition for psi(x,y,z)? For example, to satisfy psi(x,y,z) = 0, couldn't we have X(x) = a/2 when x = 0 for the first ODE, since Y(y) or Z(z) could still be zero instead meaning psi is zero. Or does the fact that X, Y and Z are independent functions preclude this.

I can't thank you enough. You've been helping me in my review for my licensure exam. Your explainations are very clear.

Thank you so much for this concise explanation.

Perfect explanation❤

As a biochemistry scientist, I’ve used this Debye-Huckel formula along side Henderson-Hasselbach equation to prove a certain mobile phase solution recipe was wrong in the lab I work at and how the pH range was not inline with the method stated.

another fantastic video thanks

thank you for amazing upload it is much appreciated.💯

thank you for the upload you actually made this make sense in my head.

Entropy is always positive, right?

Rigid rotator derivation send link sir

How exactly does changing the limits of integration equate to throwing away one of the bars on the low end side fo the integral? My intuition tells me that by moving the bound to zero, you would essentially add in a bar of e^-0. Thank you so much for this series!

Thank you so much. This was really helpful

how can you explain macromolecules transitions? (lipids, proteins and dna)

very insightful. thank you prof.

I have a doubt

i hate physical chemistry

Med student here! I remember the Shroedinger equation but we spent more time solving hydrogen and other calculus for energy states than extrapolating key concepts like thus, bravo!

Is Q here the molecular partition function or the canonical partition function?

There’s is an inproper rotation S for the Q right. If you rotate 180 degrees through the axis pointing to you out of the screen (the dot in the middle of the Q being the tip of the arrow pointing towards you) the little line of the Q is in the top left part of the circkle inverting through the center brings it back to the right bottom. 4:27

I learned from other class that this equation can lead to Le Chatelier's principle about the change of T, but I still can't understand how.

cool

From India, helped a lot for school thank you ❤❤

Thank you sir !

I would pre-heat the oxygen and fuel molecules electromagnetically. Then record the 3D volumetric temperature distribution, tracking flow of reactants. To start. And find the temperature dependent heat capacities data or models. To start. Calibrate and optimized the linked models. Track spectroscopic IR, VIS, thermal, UV, whatever is available. Share the results. Richard Collins, The Internet Foundation

Thanks for these videos. Although it is extremely unlikely that you are generating much ad revenue from my views, these videos are making a huge impact on my educational success. I'm reviewing my textbook for next semester; it might as well be Egyptian hieroglyphics without your help.

holy sh+t that was the best explaination of exact differentiation application. Explaination + & - was very helpful
